A reagent us a chemical substance applied in a chemical reaction to bring about a change in the chemical reaction process. The reagent that is appropriate to carry out the conversion is Ethanol (CH3CH2OH).

Organic Reactions are reactions taking place in organic compounds and they can take various forms such as electrophilic addition reaction or nucleophilic substitution reactions.

From the assumed diagram below, the reaction takes place in an unimolecular nucleophilic reaction SN1 mechanism in which a racemic mixture produce an organic compound and an enantiomer.

For the reaction to take place, the best organic reagent to us is known as ethanol (CH3CH2OH). This is because the organic reagent is a solvent that acts as a Nucleophile.

In the reaction, bromine (Br) is the leaving group, after it detaches from the racemic compound, it forms a carbonation in which the Ethanol CH3CH2OH attacks at the carbonation site.

Therefore, we can conclude that the Reagent necessary to carry out the conversion is Ethanol (CH3CH2OH)

The average atomic mass of element X that has two isotopes (one of 45.0 amu mass and 45% abundance and the other of 47.0 amu mass and 55.0% abundance) is 46.1 amu (option 1).  

The average atomic mass (A) of element X can be calculated as follows:

[tex] A = m_{1}\%_{1} + m_{1}\%_{1} [/tex]    (1)

Where:

m₁: is the mass of isotope 1 = 45.0 amu

m₂: is the mass of isotope 2 = 47.0 amu

%₁: is the abundance percent of isotope 1 = 45.0 %

%₂: is the abundance percent of isotope 1 = 55.0 %

Hence, the average atomic mass is (eq 1):

[tex] A = m_{1}\%_{1} + m_{1}\%_{1} = 45.0 amu*45.0\% + 47.0 amu*55.0\% = 45.0 amu*0.45 + 47.0 amu*0.55 = 46.1 amu [/tex]  

Therefore, the average atomic mass of element X is 46.1 amu (option 1).

Plate tetonics theory is the idea that different tectonic plates, are constantly moving and changing the surface of our Earth. They can move in three ways, convergent, divergent, and transform. Seafloor Spreading is like an example of divergent movement. When the plates diverge from each other it can create various changes such as creating a new sea floor. You can use seafloor spreading as an example of the plate tetonics theory.

This sunflower must be a young one because a sunflower turns toward the sun when they are young. Once they mature they will prematurally stay facing east. with this knowledge we can exclude some of tghe answers and leave the correct one remaining. It is not C becasue sunflowers do not hibernate. They lay dormante in the winter waiting for their seeds to pop out during the spring. it is not D becasue Gravitropism is a form of facing towards or away from the pull of gravity. It is nopt A because it is to simalir to Hidernation. Dormancy is staying dormant during cool temputure and ect. So our answer must be B because Phototropism is the condition that a plant growes toward light. this is why bannanas are curved and why trees grow up. So your your answer is B Phototropism.

The number of units of aluminum chloride (AlCl₃) that can be produced from 30 atoms of aluminum (Al) is 30 units

The balanced equation for the reaction is given below:

2Al + 3Cl₂ — > 2AlCl₃

From the balanced equation above,

2 atoms of Al reacted to produce 2 units of AlCl₃.

With the above information, we can determine the number of units of AlCl₃ that can be produced by the reaction of 30 atoms of Al. This can be obtained as follow:

From the balanced equation above,

2 atoms of Al reacted to produce 2 units of AlCl₃.

Therefore,

30 atoms of Al will also react to produce 30 units of AlCl₃.

Thus, 30 units of AlCl₃ were obtained from the reaction.

Answer:

Changes can occur to physical properties of a substance, but the chemical composition of the substance remains the same.

Explanation:

Physical change is a change in which there is no change in the chemical arrangement and thus there is no redistribution of atoms. No new substances are formed. There is only change in size, shape and phase etc.

[tex]H_2O(l)[/tex]→[tex]H_2O(g)[/tex]

Chemical change is a change in which there is change in the chemical arrangement and thus there is  redistribution of atoms. which leads to formation of new substances.

Answer:

To calculate half life, divide original value by 2.

1.

FOUR HALF LIVES = divide original value by 2, 4 times.

40÷ 2 = 20

20 ÷ 2 = 10

10 ÷ 2 = 5

5 ÷ 2 = 2.5g

2. AFTER TEN DAYS (TWO HALF LIVES)

140 ÷ 2 = 70

70÷ 2 = 35g

AFTER TWENTY DAYS (FOUR HALF LIVES)

140 ÷ 2 = 70

70 ÷ 2 = 35

35 ÷ 2 = 17.5

17.5 ÷ 2 = 8.75g

Exponential growth can lead to decreasing the population size, which represents an example of a NEGATIVE feedback loop. This control mechanism (negative feedback) is common in nature.

Negative feedback is a homeostatic self-regulatory process by which the output of a given system is fed back in order to reduce its internal fluctuations.

In a negative feedback, an amplified output from the system (e.g., in this case, a sudden increased population size) leads to its self-inhibition.

This control mechanism (negative feedback loop) helps to maintain the homeostatic balance of the entire system in order to reach a set point.

The molar mass of hydrogen gas H₂ is 2.016 grams.

The mass of a substance divided by its concentration, expressed in grams per mole (g/mol), is known as its molar mass.

Mass is the quantity of matter in a physical body. The product of the molar mass of the compound and the moles of the substance are defined as mass.

The mole is a SI unit of measurement that is used to calculate the quantity of any substance.

M = m /n

M = molar mass

m = mass of a substance (in grams)

n = number of moles of a substance

The mass of hydrogen is 1

The number of moles of hydrogen is 6.022 x 10²³

Hydrogen gas has a molar mass of 2.016 grams per mole. When two hydrogen atoms join forces to create a molecule with the formula H2, hydrogen gas is created.

Therefore, the molar mass of hydrogen gas H₂ is 2.016 grams

Answer: B

Explanation:

Answer:

mass of water, mw = 300g = 0.3kg

∆Tw = (80 - 20) °C

volume of air, va = 100m³

mass of air, ma = 100g = 0.1kg

∆Ta = ?

H = mc∆T

Hw = mwcw∆Tw

Hw = 0.3*4200*60

Hw = 75600J

Hw = 75.6 kJ

All the above heat energy got absorbed by air,

that is; Ha = 75600J

since it's given that the heat was absorbed by a specific amount of volume of air

then specific capacity of volume of air is

then,

ca = Ha × density

ma temp

then,

Ha = vaca∆Ta

where, ca = volumetric heat capacity of air = 0.012kJ/m³°C

75.6kJ = 100m³ × 0.012kJ/m³°C × ∆Ta

75.6 = 1.2/°C × ∆Ta

∆Ta = 63°C

63°C is the temperature change in air.

Answer: B would be the correct answer

Explanation: You will need to use P1V1/T1=P2V2/T2

So

P1= 81.0kPa /101 =0.799atm

V1=0.4L

T1=25.0C +273.15K= 298.15K

P2= 101kPa /101 = 1atm

V2=0.25L

T2= ?

T2=P2V2T1/P1V1

(1.0atm)(0.25L)(298.15K)/(0.799atm)(0.4L) =233.22K-273.15=-39.92C
